Breaking through the sub-meter level for the first time, China Unicom completes the national commercial launch of the 5.5G high-precision positioning system in the high-end manufacturing industry

China Unicom builds the country's first 5G-A high-precision positioning for commercial use

News on July 8, China Unicom Smart City Research Institute has in-depth cooperation with Purple Mountain Laboratory, Jiangsu Unicom and China Information Technology Research Institute. Suzhou Huaxing Yuanchuang Technology Co., Ltd. jointly created the country's first commercial 5G-A (5.5G) high-precision positioning in the high-end manufacturing industry, and the actual positioning accuracy exceeded the sub-meter level for the first time.

Purple Mountain Laboratory Introduction, the design goal of the 5G positioning system of Huaxing Yuanchuang Factory (Phase II) is to provide real-time sub-meter precise positioning services for material trucks, AGV robots and factory personnel in the 36,000 square meter automated assembly workshop .

The laboratory delivery team worked closely with China Unicom’s participating units to complete the system deployment on schedule despite an extremely tight deployment time. After actual measurement, the real-time positioning accuracy of the 5G positioning system has a 90% probability of reaching sub-meter level (note: resolution below 1 meter), and most areas are better than 0.5 meters.

On June 22, China Unicom and Purple Mountain Laboratory held a national commercial promotion conference for 5G-A high-precision fusion positioning at the Huaxing Yuanchuang Factory. The heads of dozens of key enterprises in the high-end equipment industry visited the system operation demonstration at the workshop.

Dr. Fan Jian, Chief Scientist of Big Data of China Unicom Group, said that this is the first time that China Unicom has improved the 5G positioning accuracy from meter level to sub-meter level: "In the past, our positioning services mainly relied on Beidou and UWB, and 5G was often only used to transmit information. Because its positioning accuracy is only 3-5 meters. At Huaxingyuanchuang, we used the 5G positioning base station + algorithm platform jointly developed with Zijinshan Laboratory for the first time to achieve an accuracy of 50-70 centimeters... It seems that the exhibition hall on the second floor of our headquarters The content should really be updated."

5G-A The full name is 5G-Advanced, also known as 5.5G. It is the technological evolution of 5G. Compared with 5G, it can achieve significant improvements in capacity, speed, delay, positioning, reliability, etc.

5G-A’s first standard version, 3GPP Rel-18, was officially frozen in Shanghai on June 18 this year. This is a milestone event in the development of the 5G industry, marking 2024 as the first year of 5G-A commercialization.
